SPF 40 indicates that a sunscreen can theoretically protect your skin from UVB rays 40 times longer than if you were not wearing any sunscreen. For example, if your skin would normally begin to burn after 10 minutes of sun exposure, SPF 40 may allow you to stay in the sun for about 400 minutes without burning. However, it’s important to apply sunscreen generously and reapply it every two hours for optimal protection. Remember that SPF only measures UVB protection, not UVA protection, so broad-spectrum products are recommended for comprehensive coverage.
